Which ISO Setting Should I Use?
By Dr. Mark Clayson Platinum Quality Author


What ISO setting should you use for everyday photography?

There is no simple answer, but have a look at the following responses to decide what is best for you:

"I usually use ISO 100, but if I realise I can't hold the camera still I increase the ISO or use a tripod"

"I most usually shoot at ISO 100, 200 and occasionally ISO 400. It annoys me that there is slight noise when I zoom on the PC. In reality you won't see it"

Exposure Digital Field Guide"I start at 100, and work up until I get a reasonable shutter speed that I feel I can cope with"

"I set the camera at 200 in good weather and 400 in bad"

"In bad light I don't go below 400"

"Inside, I start at 400, then go to 800 or more when needed. Outside I start at 100"

"If I tend to get camera shake I increase the ISO till everything is OK"

"In fully automatic mode my camera does this itself"

"I find I use 100 rarely. I prefer to go for a higher ISO to get faster shutter speeds"
ISO 15740:2005, Photography - Electronic still picture imaging - Picture transfer protocol (PTP) for digital still photography devices
So, you can see that the ISO setting is dependent upon the conditions and upon personal preferences. Experiment to find the settings that work best for you.
